The apartment was lovely, super clean and had everything we could possibly need. It's conveniently located; just a 5 min walk from the BTS station. There's also a well-stocked supermarket in the building. We didn't get a chance to try the pool or sauna facilities but they're available should you need them.
The host was extremely accommodating about check in and check out times and answered all our questions promptly.
The only shortcoming is that it's a bit cramped for 3 people; but this isn't really a problem if you're staying for a short while.
A suggestion to the host would be to include an extra pillow for the third person, we wouldn't have minded paying extra. Also note that the couch isn't long enough to sleep on but they do provide a mattress that you can roll out in the hall.
Otherwise all in all, a very positive experience. Thank you very much to our hosts! Would definitely recommend!
